 Can I bruteforce a password hash even if I dont know the . . .
Can I bruteforce a password hash even if I don't know the underlying algorithm? Will a password cracking expert still be able to brute force the password hashes? I also guess (for a public web site) that you can at least create your own "account" with a known password, so you have perhaps one known input>hash pair sha1(i), sha1(md5(i
 bruteforce sha1 with hashcat
hello everybody! i have a pretty simple 20 lenght hash to bruteforce with SHA1 algo and 8 numbers length, salt has to be 0000000000000000 ===== hashcat log=====
 security  Whats the big deal with brute force on hashes . . .
Brute forcing Running sha1(md5(text)) will only double the time it takes to find the original string This is nothing in terms of security FOr instance, if you have 128bits of output space for each algorithm, and it takes 1 hour to brute force, then it will take 2 hours to run the same brute force twice to get the original string
 sha 1  Is the SHA1 hash of MD5 hash of a password secure . . .
I will not go into the details of if, overly simplified it is a heavily compressed password hash dictionary Another thing to note, that once the password database is leaked, an attacker has also the possibility to brute force, by calculating the SHA1 of each possible combinations Takes time, but with GPUs it

 brute force  How can SHA256hashes as input to MD5 be . . .
It's very clear to me that this file contains short passwords and passwords which appear in a dictionary, since you can get them by brute force What I don't understand is: Why are there SHA256 hashes in this file? You simply can't input all SHA256 hashes into MD5 because the input space is way too big
 1 MD5 and SHA1 Collision Attacks: A Tutorial
However, MD5 and SHA1 are vulnerable to collision attacks based on diﬀerential cryptanalysis MD5 is completely broken in that collisions can now be found within a few minutes on modern machines SHA1, while not completely broken, is showing signs of weakness That is, the attacks on SHA1 have a lower time complexity than a brute force
 hash  How to brute force a password that has been hashed . . .
By and large, phishing and especially spear phishing are much more likely to succeed on a well maintained secured system than brute force, though brute force is a great way to achieve DOS as well There is a whole discipline based on this topic and soooooo much more to consider
